Quote from max401:
It takes premium fuel. The bigger first question, is the price even a good value? All BMW V8's until 96 were prone to abnormal cylinder wall wear and the factory would warrant them, but only to 100K. Since a fix wasn't made to this engine until much later, the only way BMW could save its reputation was to replace the engines with the same defective design, until they could find the problem. They eventually found that the blocks cast in Nikasil reacted with the high sulfer content of US gasoline, but that their flagship V12 blocks made from Alusil, had no such problem.
If this 5 has an original engine or a Nikasil replacement short block, you would be out of luck, Some cars had as many as 4 short blocks. Here's how to determine which which compound the engine is cast in:
You have to get underneath the car and fine the casting number located below the number 3 cylinder:
Nikasil M60B40 1 725 963 or 1 742 998
Alusil M60B40 1 745 872
Alusil M62B44 1 745 873
